    • An exhaust obturator comprises a tubular housing (11a) having a butterfly valve (14a, 15) journalled in the wall thereof. The butterfly spindle (14a) passes through a chamber (24, 25) on one side of the housing and carries a sealing ring (26) thereon and located in the chamber (24, 25). The sealing ring (26) is a close sliding fit on the spindle (14a) when the obturator is closed, exhaust gas pressure on the upstream side enters the chamber (24, 25) and urges the seal (26) against a cover plate (23a) thereby to prevent the escape of exhaust gas to atmosphere. The chamber (24, 25) is preferably vented to the downstream side. The seal may alternatively be biased by resilient means.
